Back Applicator Band With Non-Absorbent Bristles for Fluid Spreading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin treatment devices for applying fluid treatments on the back lack a stretchable mechanism and bristles that can effectively spread the treatment without absorbing it, leading to inefficiency and discomfort.
Innovation Solution
A skin treatment device featuring an elastomeric band that stretches across the back, a central block with attached fluid-impermeable bristles, allowing for even distribution of fluid treatments without absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an applicator pad is used to apply fluid treatment on the back, then the treatment can be applied to the skin surface, but the applicator pad absorbs the fluid treatment reducing application efficiency
Solution Approach 1:
The patent applies the opposite principle by using non-porous, fluid-impermeable materials for the bristles. The bristles are specifically designed to be non-absorbent so that they do not take in the fluid treatment, thereby preventing loss of substance and maintaining application efficiency.
2Productivity
If a rigid applicator is used to spread fluid treatment, then the treatment can be distributed across the back, but it causes discomfort and potential skin irritation
Solution Approach 1:
The patent applies local quality by making different parts of the device have different properties. The bristles are made soft and flexible at the contact point to be gentle on the skin, while the block and band provide the necessary structural rigidity for effective treatment distribution across the back.
Solution Approach 2:
The elastomeric band provides dynamic adaptability, allowing the device to conform to the contours of the back. This flexibility enables the bristles to maintain gentle contact with the skin surface while still achieving effective treatment distribution across varying anatomical landscapes.
3Area of stationary object
If a non-stretchable applicator is used, then the structure can be simple, but it cannot be stretched across the entire back surface reducing coverage area
Solution Approach 1:
The elastomeric band transforms the device from a static to a dynamic structure. It can be stretched to accommodate the full width of the back, significantly increasing the coverage area. The band's elastic properties allow it to expand and contract while maintaining functional integrity.
Solution Approach 2:
The elastomeric band functions as a flexible element that can be stretched across the back. This flexible component allows the device to adapt to different body sizes and shapes, maximizing the area of stationary object (back surface coverage) without significantly increasing device complexity.
4Ease of operation
If the user applies treatment without assistance, then independence is achieved, but stress and fatigue on the user's joints increases
Solution Approach 1:
The elastomeric band acts as a counterbalancing mechanism, utilizing elastic tension to support the weight of the block and bristles. This reduces the force the user's joints must exert to hold and maneuver the device, enabling independent application without excessive joint stress.
Solution Approach 2:
The flexible band allows the device to be positioned and held in place with minimal effort by distributing the mechanical load. The elastic tension in the band creates a balanced state that reduces the energy required to maintain the device in the correct position during application.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and comfortable application of fluid treatments over the entire back surface without assistance, reducing stress and fatigue on the user's joints.
Implementation Method 1
an elastomeric band which can be extended across a user's back. The elastomeric band is stretchable to such that tension in the elastomeric band enables the elastomeric band to be compressed against the user's back
Implementation Method 2
Each of the plurality of bristles is comprised of a fluid impermeable material thereby enabling the plurality of bristles to spread a fluid skin treatment across the user's back

AI summary
A skin treatment applicator device includes an elastomeric band which can be extended across a user's back. The elastomeric band is stretchable to such that tension in the elastomeric band enables the elastomeric band to be compressed against the user's back. A block is attached to the elastomeric band and the block is placed against the user's back when the user stretches the elastomeric band across their back. A plurality of bristles is each attached to the block thereby enabling the plurality of bristles to be pressed against the user's back when the user stretches the elastomeric band across their back. Each of the plurality of bristles is comprised of a fluid impermeable material thereby enabling the plurality of bristles to spread a fluid skin treatment across the user's back.
